A handle's usecount used to be incremented once during the mmap ioctl, and decremented when the mapping is closed by the kernel. However, that fails if a mapping cloned, for example if the mapping was split due to a munmap, or (presumably) during fork, as the decrement will then happen for each cloned mapping. Therefore increment the usecount when a mapping is opened. Also fix a BUG_ON() that would have caught this bug, if it wouldn't have done the check by checking if the unsigned usecount field is less than zero.

nvhost_3dctx_alloc_common correctly checks the return value of an allocator function, and attempts to perform cleanup. However, this particular allocation API returns ERR_PTR values in case of failure, which then gets passed to the deallocation function, causing a crash. Also, the return value of that allocator API is checked with IS_ERR in some places, and with IS_ERR_OR_NULL in others. For consistency and avoiding surprises if the allocation implementation changes, use IS_ERR_OR_NULL in all places.

2012-08-22video: tegra: host: Fix crash if allocation failsTuomas Tynkkynen
nvhost_module_remove_client assumes that a client structure to be freed exists in the linked list. However, if an allocation fails in nvhost_module_add_client, no client structure is allocated, and during cleanup, nvhost_module_remove_client would then attempt to free an invalid pointer.

do_heap_alloc locates a suitable free block from a nvmap heap given a size and alignment. Unfortunately, if a heap block happens to be smaller than the alignment passed to the function, an integer overflow will occur, and a block that's too small gets accidentally returned.

nvmap_map_into_caller_ptr takes a memory handle from usermode and adds a memory mapping for the handle. However, the handle is not checked for being allocated. An unallocated handle would cause a kernel panic later on from a NULL dereference.
